This paper discusses a rare case of a 49-year-old female diagnosed with a central nervous systemisolated neoplasm with histiocytic features, classified as histiocytic neoplasm, not otherwise specified (NOS). Despite comprehensive histopathological and genetic studies, accurately diagnosing the case proved challenging. Initial surgical findings and frozen biopsy suggested a low-grade glioma; however, subsequent immunohistochemistry and genetic analysis excluded known histiocytic subtypes such as ALK-positive histiocytosis and Erdheim-Chester disease. The patient’s condition improved following occupational rehabilitation therapy for right upper motor weakness, as well as anticonvulsant and radiation therapy, and her neurological condition remains stable. This case underscores the diagnostic challenges of Histiocytic Neoplasms and the necessity for interdisciplinary collaboration and sophisticated diagnostic techniques.

ObjectiveTo investigate the clinical efficacy and potential mechanism of Shengmai Jiuxin decoction in the treatment of acute decompensated heart failure （ADHF） with the traditional Chinese medicine （TCM） pattern of Qi and Yin deficiency， Yang deficiency， and blood stasis. MethodsA total of 68 patients diagnosed with ADHF of Qi and Yin deficiency， Yang deficiency， and blood stasis type were randomly assigned to an observation group （34 cases） and a control group （34 cases）. Both groups received conventional Western medical treatment， while the observation group was additionally administered Shengmai Jiuxin decoction. Parameters compared before and after treatment included： TCM syndrome score， TCM syndrome efficacy， New York Heart Association （NYHA） functional classification， left ventricular ejection fraction （LVEF）， N-terminal pro-B-type natriuretic peptide （NT-proBNP）， six-minute walk distance （6MWD）， hypoxia-inducible factor-1 alpha （HIF-1α）， vascular endothelial growth factor A （VEGF-A）， Caspase-3， and the number of rehospitalizations for heart failure within one month after discharge. ResultsThere were no significant differences in sex， age， vital signs， or underlying diseases between the two groups. Compared with baseline， both groups exhibited significant reductions in TCM syndrome scores， NT-proBNP， and HIF-1α levels （P<0.01）， as well as significant increases in 6MWD， LVEF， VEGF-A， and Caspase-3 levels （P<0.05， P<0.01）. After treatment， the observation group showed significantly greater reductions in TCM syndrome score， NT-proBNP， HIF-1α， and Caspase-3 levels compared with the control group （P<0.05） and significantly greater increases in 6MWD， TCM syndrome efficacy， and VEGF-A levels （P<0.05）. No significant differences were observed between the groups in NYHA functional classification， LVEF， or the number of rehospitalizations for heart failure within one month after discharge. No drug-related adverse events were reported in either group during the treatment period. ConclusionShengmai Jiuxin decoction can improve cardiac function and clinical symptoms in patients with ADHF of Qi and Yin deficiency， Yang deficiency， and blood stasis type. Its mechanisms may be related to the regulation of the HIF-1 signaling pathway by modulating targets such as HIF-1α， VEGF-A， and Caspase-3.

Given the systematic, rigorous, and practical characteristics of medical disciplines, ensuring the teaching quality of online courses has become a significant focus. In traditional teaching models, teaching supervision is an important method to guarantee instructional quality, and introducing teaching supervision into online teaching activities is of great significance. This article systematically reviews and summarizes the domestic and international experience of conducting online medical courses. We explore the instructional supervision of online medical courses from the following perspectives: the meaning of supervision, the necessity of online supervision, online supervision methods and technical approaches, the feedback and application of supervision information, and the establishment of a standardized online supervision process.
